Welcome to the Quantum Device Theory (QDT) Research Site.

Group Research Goals

We are performing theoretical studies of physical devices that are governed by the laws of quantum physics. One of our goal is to faciliate the realization of quantum computing using nanoelectronic elements. We are collaborating with a number of experimental laboratories in this area.

Here are some recent popular introductions to our work

• Quantum technology (presentation given at the IQC open house, June 2007) [pdf 476 kB]
• Quantum physics of electrical circuits (article in Phys13News, 2006) [pdf, 2.8 MB]
• Circuit Quantum electrodynamics - Photon lab on a chip (Nature News and Views, 2007)
• Strongly driven qubits - A shift in spectroscopcy (Nature, August 2008)
• Review article on superconducting qubits (Nature, June 2008)
• Article in the UW Engineering newspaper (January 2010)
  

Current projects:

• Superconducting quantum bits
• Quantum bits based on semiconductor nanostructures
  
• Optimal quantum gates in imperfect qubits
• The physics of the measurement process with nonlinear detectors
• Quantum phenomena in nonlinear systems, e.g. dynamical tunneling
• Scalable architectures for quantum computers with realistic error thresholds
• Circuit quantum electrodynamics
• Decoherence from structured environments
